Final answer:
Test tubes are the tubes that typically go to the Chemistry Department to be tested. They are used to hold and mix small amounts of liquids, as well as observe chemical reactions. Test tubes are an essential tool in chemistry labs for conducting experiments and analyzing substances.
Step-by-step explanation:
The tubes that typically go to the Chemistry Department to be tested are test tubes. In a chemistry lab, test tubes are commonly used to hold and mix small amounts of liquids or to observe chemical reactions.
These test tubes can be made of glass or plastic and come in different sizes, typically ranging from 10 ml to 20 ml in volume. They are an essential tool in the field of chemistry for conducting experiments and analyzing substances.
